Innumerable as the stars of night,
Or stars of morning, dew-drops, which the sun
Impearls on every leaf and every flower.
(Milton, Paradise Lost, 745-747)

Innumerable as the stars of night makes sense of brain lesions, by re-contextualising them with other enchanting and mysterious spectacles of light.
